Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

Rule 1159 was amended to satisfy the provisions of Health & Safety Code (H&S Code) §39614(d) which req uires

the adoption of readily available, feasible and cos t-effective control measures for Particulate Matter (PM) from a

list of potential local control measures promulgate d by the California Air Resources Board (CARB). Th e level of

control contained in the proposed amendments to Rul e 1159 has been determined to be readily available, feasible

and cost-effective based upon an analysis and recom mendations made in the feasibility analysis for sta tionary gas

turbines included in the Technical Discussion of th e Staff Report. A complete summary of rule changes is

contained in the Staff Report, §(VI)(D)

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: The proposed amendments to Rule 1159 – Stationary Gas Turbines do not cause the release o f additional air

contaminants or create any adverse environmental im pacts because all existing turbines in the District are subject to

alternative federal NOX RACT limits at which they a re currently permitted. Section (C)(1)(a) Table 1 proposes NOx and

CO compliance limits which would apply to future in stallations of only very small stationary gas turbi nes, while larger

turbines would be subject to New Source Review. Th is rule amendment updates federal RACT.
